Dow and Menshen bring sustainable design to spouted pouches

Dow and Menshen announce the new transformative Reverse Spout Sealing Technology that enables the production of spouted pouches made of mono-material films. This exciting technology allows converters to address the recycling criteria for flexible packaging and can help brands meet their sustainability packaging goals.

“We basically reversed the idea of where and when the heat needs to be applied during the spout sealing process”, explained Dr. Peter Sandkuehler, global application technology leader at Dow’s Packaging & Specialty Plastics business. “By transferring the heat from the pre-melted spout base directly to the sealant layer of the film, we’ve solved two challenges at the same time: how to easily seal spouts to mono-material films, and how to prevent the hard spout ribs from cutting into the film.”

The introduction of the reverse spout sealing technology is the result of a remarkable three year joint development between Dow and Menshen to work who are working with a number of partners on technology integration and assist brand owners and converters to put the new sealing approach into practice.
